Review: Excellent stone - really takes my edges to the next level - Without this stone, I can still get a pretty good edge with just the green X-fine but THIS stone defintely takes my edges to the next level - razor sharp and very polished. At the new price of $14, don't pass up on this. I paid $18 and they dropped the price right afterwards ... grrr :-) Maybe someday I'll also get setup for stropping with some diamond paste or 3m abrasive lapping pads but at the moment I don't feel that these are necessary for me since the DMT xxf does such a great job. I can literally shave with any of my edges honed with this stone. I'll usually complete a full v profile with this stone and then add a microbevel using ONLY this stone at the very end, with either 1 or 2 steps up on the aligner (depending on the blade). Works like a charm! My only complaint is that shipping took a while for this item, even though it was listed as in stock.
Review: Quality Product - Having used this sharpening tool for many years I have not found anything to complain about. This is a quality product from DMT. I use it to get a keen edge on my wood carving knives and to touch up a chisel or two. Two knives that I use when camping , both with heavy blades and with a unique curvature to the blade, this narrow tool makes it a breeze to touch up the edge when needed. When used properly , this tool will last for many years. I would recommend to friends and will purchase again, when needed.

### ⭐⭐⭐⭐⭐ Great as honing steel replacement. Awsome stone.
*by N***O on August 13, 2013*

Excellent stone when used in conjunction with the aligner kit. I've essentially phased out using my water stones in favor of the DMT system. These particular stones have a small break in period and will arrive feeling a little more aggressive than a typical waterstone of equal grit/micron size. It's not a problem, and after a couple of uses it will become superior in function compared to a water stone. No mud, always flat, fast cutting and it can be used dry. On carbon steel knives, with the right bevel angle you can very easily attain a 3 micron non-toothy edge that is literally hair whittling sharp. I currently use this particular DMT stone as a replacement for my honing steel/rod. Its certainly less convenient than a steel, but the tradeoff of being able to produce a much longer lasting edge than you can with a steel rod is worth the effort.
